Client server architecture

 Client server architecture

Client-server architecture is distributed model representing dispersed responsibilities among independent computers integrated across a network. Therefore, it's easy to replace, repair, upgrade and relocate a server while client remains unaffected.


Advantages of Client-Server Architecture:

Organizations often seek  opportunities to maintain services and quality competition to sustain its market position with the help of technologies. Deployment of client-server computing in an organization will effectively increase its productivity through the usage of  cost-effective user interface, enhanced data storage, vast connectivity and reliable application services
  • Improved Data Sharing: 
Data is retained by usual business processes and manipulated on a server is available for designated users (clients) over an authorized access.
  • Integration of Services: 
Every client is given the opportunity to access corporate information via desktop interface eliminating the necessity to log into a terminal mode or processor. 
  • Shared Resources Amongst Different Platforms: 
Application used for client-server model is built regardless of the hardware platform or technical background of the entitled software (operating system software) providing an open computing environment, enforcing users to obtain the services of clients and servers (database, application and communication services)
  • Data Processing Capability Despite the Location: 
Client-server users can directly log into a system despite of the location or technology of the processors.
  • Easy Maintenance: 
Client-server architecture is distributed model representing dispersed responsibilities among independent computers integrated across a network. Therefore, it's easy to replace, repair, upgrade and relocate a server while client remains unaffected. This unaware change is called as Encapsulation.
  • Security: 
Servers have better control access and resources to ensure that only authorized clients can access or manipulate data and server updates are administered effectively.


 1. Monolithic architecture

2.    Layerd archtecture.

3.     Virtual machine architecture

4.     Exokernel architecture

5.    Client server architecture 


6.     Micro kernel architecture

Disadvantages of Client-Server Architecture.
  • Overloaded Servers: 
When there are frequent simultaneous client requests, server severely get overloaded, forming traffic congestion.
  • Impact of Centralized Architecture: 
Since it is centralized, if a critical server failed, client requests are not accomplished. Therefore, client-server lacks the robustness of a good network.

Multi processing system

  Multi processing system ·           Multi processesor system is the sytem that contain two or more processors or CPUS and has ability to simultaneously execute     several programs. Hence the name multi-processor In such a system, multiple processor share the clock, bus, memory and peripheral devices. ·           A multi processor system is also known as parallel system ·           Multi processor system are categorized into two different types:                single user operating system    2.        Multi user operating system   3.         Batch processing operating system 4.        Multi programming operating system   5.       Multi tasking operating sy...

Real-time system

  R eal-time system ·           In a real time operating system, a job is to be completed within the    rigid time constraints otherwise job loses its meaning. ·           A real time system function correctly only if it returns the correct result within its time constraints ·           Thus, in a    real-time system, the correctness of the    computation not only depends upon the logical correctness of the computation but also upon the time at which the result is produced. R eal-time system In a real time system various functions like process scheduling, memory management, I/O management and file  management are performed as follows : 1.         Process scheduling  . the real time system uses priority based pre-emptive scheduling. each process is assigned a certain level of ...

Virtual Machine Architecture

  Virtual Machine Architecture A virtual machine can exist as a standalone machine or it can exist within a vApp. A virtual machine is a software computer that, like a physical computer, runs an operating system and applications. The virtual machine consists of a set of specification and configuration files and is backed by the physical resources of a host. Every virtual machine has virtual devices that provide the same functionality as physical hardware are more portable, more secure, and easier to manage. Virtual machines can be standalone, or they can exist within a vApp. A vApp is compound object composed of one or more virtual machines as well as one or more networks. 1.    Monolithic architecture 2.     Layerd archtecture . 3.     Virtual machine architecture 4.       Exokernel architecture 5.      Client server architecture   6.       Micro kernel architecture The following figure ...

Batch Processing Operating System

  Batch processing system ·           Batch processing is one of the oldest method    of running the programs ·           The computer in the past were very large in size and their I/O devices were very different from those that are used today. The job processing was not interactive as it is today. ·           The user did not interact directly with computer system.   ·           The process scheduling , memory management, file management and I/Omanagement functions are quite simple in batch processing system   1.         Process scheduling (i.e. allocation strategy for a processor is typically in order of their arrival i.e. first come first served(FCFS)basis.   2.         Memory management  is done by divi...

Multitasking System

  Multitasking system ·           Technically , multitasking is same as multi programming ·           In a multitasking operating system, s single user can execute multiple programs at the same time ·           We can also say, multitasking is the system capability to work on more than one job or process at the same time. ·           It means that whenever a job needs to perform I/O operation, the cpu can be used for execting some other job                                                        diagram of multi tasking     ·           There are two type of multitasking : 1.       ...
